Abducted!

So apparently Leo has been abducted. Until some demands are made, we're probably not going to contact the authorities. We're putting together an investigation. Here's what we know:
1. Leo was hanging out on the stage.
2. He was last seen during the snack time.
3. He disappeared and this note was found in his place.
4. It seems that everyone has an alibi as to where they were when he went missing...
If you have any evidence or clues, please let us know. We'll make sure to pass it on to the investigator(s).
